Struct Narrative 

pub struct Narrative {
    pub id: NarrativeId,
    pub title: String,
    pub events: Vec<Event>,
    pub metadata: NarrativeMetadata,
    pub tags: Vec<String>,
}

A collection of related events forming a coherent story.

Narratives are the primary container for organizing events into meaningful stories with geographic and temporal structure.

Examples

use spatial_narrative::core::{Narrative, Event, Location, Timestamp};

let mut narrative = Narrative::builder()
    .title("Hurricane Timeline")
    .description("Tracking the hurricane's path")
    .category("disaster")
    .build();

narrative.add_event(Event::builder()
    .location(Location::new(25.0, -80.0))
    .timestamp(Timestamp::now())
    .text("Hurricane makes landfall")
    .tag("landfall")
    .build());

Fields

id: NarrativeId

Unique identifier.

title: String

Title of the narrative.

events: Vec<Event>

Events in this narrative.

metadata: NarrativeMetadata

Narrative metadata.

tags: Vec<String>

Categorical tags for the narrative.

Implementations

impl Narrative

pub fn new(title: impl Into<String>) -> Self

Creates a new narrative with the given title.

pub fn builder() -> NarrativeBuilder

Creates a builder for constructing a Narrative.

pub fn events(&self) -> &[Event]

Returns the events in this narrative.

pub fn events_mut(&mut self) -> &mut Vec<Event>

Returns a mutable reference to the events.

pub fn len(&self) -> usize

Returns the number of events.

pub fn is_empty(&self) -> bool

Returns true if the narrative has no events.

pub fn add_event(&mut self, event: Event)

Adds an event to the narrative.

pub fn remove_event(&mut self, id: &EventId) -> Option<Event>

Removes an event by ID.

pub fn get_event(&self, id: &EventId) -> Option<&Event>

Finds an event by ID.

pub fn get_event_mut(&mut self, id: &EventId) -> Option<&mut Event>

Finds an event by ID (mutable).

pub fn events_chronological(&self) -> Vec<&Event>

Returns events sorted by timestamp.

pub fn filter_spatial(&self, bounds: &GeoBounds) -> Vec<&Event>

Filters events by spatial bounds.

pub fn filter_temporal(&self, range: &TimeRange) -> Vec<&Event>

Filters events by time range.

pub fn filter_by_tag(&self, tag: &str) -> Vec<&Event>

Filters events by tag.

pub fn bounds(&self) -> Option<GeoBounds>

Returns the geographic bounds of all events.

pub fn time_range(&self) -> Option<TimeRange>

Returns the time range spanning all events.

pub fn all_tags(&self) -> Vec<&str>

Returns all unique tags used by events in this narrative.

pub fn add_tag(&mut self, tag: impl Into<String>)

Adds a tag to the narrative.

pub fn filter<F>(&self, predicate: F) -> Narrative

where F: Fn(&Event) -> bool,

Creates a new narrative containing only events that match the predicate.

pub fn merge(&mut self, other: Narrative)

Merges another narrative into this one.

Trait Implementations

impl Clone for Narrative

fn clone(&self) -> Narrative

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Narrative

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Narrative

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Narrative

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Narrative

fn eq(&self, other: &Narrative) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Narrative

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
